The Pentax lenses in general are simply superb. Even the new DA pancakes are well regarded and I have a few galleries on my site with these lenses. The 31 f1.8 is pretty heavy compared to the new DA lenses but it certainly returns some great images. As I've said before I will have to put this on a NEX camera to see how it performs. Saddly, time is a problem.

I think this image says it all about these lenses. Great contrast and rendition. This was shot wide open so you could call it sharp. If it's like this wide open just think what it's like stopped down a couple of notches.

This one from the FA 31 f1.8 I like a lot. The sun shon through the leaves to where my wife stood illuminating just her face. I hadf to be quick on this one as it didn't last long, just a few seconds. I was quite surprised how the focusing seems to be bang-on. Practice makes perfect.

I'm going to be trying these lenses out on the Sony-5N pretty soon. I think I'm going to like the result. 

I just got around to processing some images from the Pentax 31 f1.8 adapted for the E-P3 m4/3 camera. Since I like to use these lenses wide open, it is sometimes very difficult to nail the focus where you want it, especially at f1.4 or f1.8. The depth of field is so small it takes me some time to get it right. This has caused many a misfocused image rady for the rubbish bin. However, practice makes perfect and that applies here too. The more you pictures you take, the easier it gets but, each lens is different and you have to get used to each one. So, if you are like me, a lens nut, then it takes time to get the best out of each and every lens.

I think I nailed focus here though.
